(AllHipHop News) Just Blaze has produced for some of the top rap stars in the business. Over his 20 year career, Blaze has certainly racked up countless records that never made it out of the vault. The New Jersey born producer/DJ shared a few of those hidden gems during a set on DJCity’s MikiDz Show.

The session included Blaze debuting an unused track from Jay Z’s The Blueprint 3 as well as instrumentals that were intended for Drake, Jay Electronica, Jeezy, Slaughterhouse, and Cam’ron. The 38-year-old production whiz previously premiered unreleased music from Jay, Cam, Kanye West, Usher, and others during Q-Tip’s Abstract Radio show.
